Well, two of those are centrebacks who are notoriously more expensive than full backs
Cancelo was an odd one as he had an overinflated price tag as it was a bit of clever financing as we sold Danilo for £34mil to Juve (think of the deal between Barca/Juve with Arthur and Pjanic)
Also he had over 100 caps between big European clubs Valencia, Inter Milan, Juventus and had been part of Seria A team of rhe year with Inter
Walker was arguably the most consistent if not the best RB in the country for the last 5 or so years before his move, making PFA team of the year 2 times....Plus he was bought from a top 4 contender
Mendy was a disaster, but he'd just powered Monaco through the champions league and was thought of as one of the best in the world that season....also exactly what we needed....but injuries completely drained his ability as he was very pace/power dependent
So on paper, buying your player of the season really doesn't compare to the Walker and Cancelo, two of the best full backs in the world when we bough them
The Ake figure is actually a good one. Ake, a CB, was Bournemouth two time player of the season but that was also Pre-Covid prices
Think £40mil is fair for cucurella, it would put him behind only Hernandez, Cancelo, Mendy, Hakimi, Walker, Wan Bissaka, Chillwell and Ferland Mendy for most expensive full back transfers of all time
Hardly disrespectful offering the same/more than the cost of Zincheko, Tierney etc. As a first bid
